The purpose of this study is to develop and evaluate unidimensional models that can handle semiordered data within scale items (i.e., items with multiple ordered response categories, and one additional nominal response category). We apply the models to scale data with not applicable (NA) responses to compare the model performance to conditions in which NA responses are treated as missing and ignored. We also conduct a small simulation study based on the operational study to evaluate the parameter recovery of the models under the operational conditions. Findings indicate that the proposed models show promise for (a) reducing standard errors of trait estimates for persons who select NA responses, (b) reducing nonresponse bias in trait estimates for persons who select NA responses, and (c) providing substantive information to practitioners about the nature of the relationship between NA selection and the trait of measurement.  相似文献

In this study, teaching assistants (TAs) were trained to spend 4 min each day on a precision teaching programme with selected pupils, whose progress in word recognition was a cause for concern. Words were taken from “The National Literacy Strategy Framework for Schools”. The sessions were set up to be “fun” times. All the pupils made progress and the majority were also reported to have improved in self‐esteem and confidence. Junior boys particularly benefited from this stringently targeted regime with immediate feedback of results. Some had been displaying behaviour difficulties, and TAs also reported improved social performance and attendance rates.  相似文献

In one study, parameters were estimated for constructed-response (CR) items in 8 tests from 4 operational testing programs using the l-parameter and 2- parameter partial credit (IPPC and 2PPC) models. Where multiple-choice (MC) items were present, these models were combined with the 1-parameter and 3-parameter logistic (IPL and 3PL) models, respectively. We found that item fit was better when the 2PPC model was used alone or with the 3PL model. Also, the slopes of the CR and MC items were found to differ substantially. In a second study, item parameter estimates produced using the IPL-IPPC and 3PL-2PPC model combinations were evaluated for fit to simulated data generated using true parameters known to fit one model combination or ttle other. The results suggested that the more flexible 3PL-2PPC model combination would produce better item fit than the IPL-1PPC combination.  相似文献

This paper offers a critical examination of the student experience of a new part-time degree in Early Childhood Studies. The current Scottish Executive emphasis on encouraging lifelong learning through improved access, extended participation and the provision of opportunities for progression has created a climate where studying part-time while continuing to work is receiving active government support. The degree examined in this paper offers Early Years staff the opportunity to continue their personal development as they work and it fits well with the increasing recognition of the need for a more valued and qualified workforce in Early Years. Data on student experiences was collected at the end of the first calendar year of the course through structured student evaluation of the modules delivered and through student responses to a 'Support for Learning Agenda'. The agenda was used twice during the year to encourage reflective comment about ongoing participation in the course and also as the basis for discussion with a personal tutor. Results from the two sets of data highlighted the complexity of balancing work, personal and study commitments in part-time study. The issues which emerged for discussion and further investigation included expectations of the learning environment, the difficulties of making transitions from one type of learning environment to another and a number of issues related to combining study and work. The paper concludes by considering the implications for policy and practice.  相似文献

The purpose of this paper is to describe the school-based contextual constraints perceived by beginning elementary teachers as they attempted to enact their visions of effective mathematics teaching and the components of a mathematics-specific, university-based induction program designed to support elementary teachers in their teaching of mathematics. A significant number of beginning teachers in the program indicated that curriculum pacing guides and grade level teachers often discouraged their enactment of effective mathematics teaching. We describe the components of the induction program in general and then discuss the specific ways that program mentors, who were elementary teachers with expertise in mathematics teaching, supported beginning teachers in navigating the constraints identified. Data suggest that supporting teachers’ pedagogical agency to navigate local school contexts should be an additional consideration in teacher preparation and induction programs.  相似文献

This study examines the relationship between social background factors and educational achievements. It draws on unique data from London LEAs. The paper illustrates detail analysis on levels of disadvantage in schools and the complexities of judging school performance including discussion on the potential of z-score indicators to measure the levels of deprivation in urban area schools. Overall, the findings from the empirical evidence suggests that there is a strong relationship between disadvantage and examination success, with LEAs located in non-deprived areas tending to obtain higher percentages 5 + A*-C good GCSE passes. Further analysis of the relationship between pupils background and school achievement also confirmed, by and large, that schools with a higher number of disadvantaged families do less well than schools where, a small proportion of their pupils come from disadvantaged families. The paper concluded that uncontextualised performance table is fundamentally flawed and argued for the need to compare like with like and move beyond league table approaches of comparing schools. Policy implications are highlighted as well as practical suggestions.  相似文献

The study tries to disentangle the processes of left-right discrimination on self and on other refrents. Ninety-six 4- to 7- year old children were individually given several situations requiring left-right discrimination on self and decentration. Three related tasks were also presented: a lateralization task, an orientation task and a projection task. A semi-structured interview was finally conducted in which children explained their comprehension of left-right discrimination. Body rotations were recorded in the various tasks and during the interview. Correct deictic gestures and a measure of the children’s reasoning in the interview were also obtained. With respect to left-right discrimination on self, it was hypothesized that this kind of knowledge is anchored in the body and related to the lateralization measure. With respect to decentration, a task analysis was conducted. It was predicted that orientation and projection tasks are simple tasks mastered before left-right decentration, a complex task into which the simple tasks have to be integrated. Decentration requiring the coordination of an invariant component and of the variant component of orientation was expected to be positively correlated with body rotations. Different methodological improvements referring to reliability and validity were also introduced into the different assessment procedures. Results are confronted with the Piagetian hypothesis of interiorization of overt action into representation. An alternative hypothesis is proposed: it ties together the constellation of results obtained in the present study, and in recent studies referring to children’s cognitive development and adult’s nonverbal behavior.  相似文献

Abstract

We hypothesized that students use the message behind teacher emotions to interpret the cause of their failure and to form competence beliefs; hence, in failure situations teacher anger could be beneficial. In Experiment 1, participants made judgments about another student’s failure in the face of teacher pity versus anger. Lack of ability attributions were made and low competence was perceived, when pity was interpreted as the teacher attributed the failure to lack of ability. Lack of effort attributions were made when anger was interpreted as the teacher attributed the failure to lack of effort. Experiment 2 replicated and extended these findings by examining students responses to their own failure. Findings imply that expressing anger is less detrimental than many teachers suppose.  相似文献
